Yes. Cover the Alkyd Surface with Liquitex Clear Gesso first, then paint in acrylic. I've done this before with no ill effects whatsoever.
To determine whether a paint is alkyd or acrylic, check the label for specific terms; alkyd paints typically indicate they are oil-based, while acrylic paints are water-based. Additionally, you can perform a simple solvent test: apply a small amount of mineral spirits to a cotton swab and rub it on the paint; if it softens or dissolves, it’s likely alkyd. Conversely, if it remains unaffected, it’s likely acrylic. Lastly, the drying time can also be a clue; alkyd paints generally take longer to dry than acrylics.
In the past oil paints referred to either petroleum based paints or linseed based paints. Today in the USA petroleum based paints are no longer sold and it is difficult to find linseed based paints though they do exist with a small proportion of linseed oil. Alkyd paints are made with synthetic oil and are readily available and have come to be known as "oil" paint.
Alkyd is used to create paints that will dry extremely hard and will resist multiple cleanings. Normally, alkyd paints are oil-based, but there are now water based varieties. You can find alkyd paints on doors and trim both inside and outside houses.
Traditionally, alkyds are found in solvent-based paints that must be reduced with paint thinner or mineral spirits. "Waterborne alkyd" is a generic term to refer to an alkyd resin that can be used in a water-thinnable paint. Because alkyds are not miscible with water, a chemical modification is sometimes used to produce a hybrid alkyd resin - often acrylic/alkyd or urethane/alkyd - that is compatible with water. These hybrids are often categorized generically under the term waterborne alkyds. A pure alkyd can be emulsified in water using appropriate surfactant combinations. This type of surfactant-stabilized alkyd emulsion has been sometimes referred to as an "alkyd latex." Different resin manufacturers use varying terminology to describe waterborne alkyds with the terms alkyd emulsion, alkyd dispersion, and alkyd latex being among the most common.
Enamel paint is oil or alkyd. Alkyd paint is probably the most well known type of oil paint available on the market. The word alkyd actually refers to the synthetic resin used as a binder in the paint. This would be the oil in the paint, most commonly vegetable oil. Alkyd paints also come in a wide variety of finishes making it ideal for multiple different projects. Alkyd paint is very resistant to normal wear and tear. Thus, this type of paint is used commonly in "high traffic" type areas. This would include doors and trim within a home and also items that would need painting in the kitchen and bathroom such as cabinets. The alkyd paint will hold up to all the abuses that may come its way. Acrylic enamel is a water based full gloss usually for interior surfaces only. The gloss is nearly as high as gloss enamel but it is not quite as durable. One advantage is that if you are using white it does not discolor over time as much as alkyd based enamel. Also from a professional point i have never found the finish to be as good as enamel with less than three coats.

Alkyds can be modified (blended with ) acrylic resins/emulsions or other polymers such as phenolic resins or urethanes, so all acrylic alkyds are modified alkyds, but not all modified alkyds are acrylic alkyds. Both are pretty general terms, but modified alkyd is much more vague and proprietary. The term "Acrylic Alkyd" is usually reserved for alkyds which have been chemically modified with acrylic monomers such as methyl methacrylate, methacrylic acid, styrene, vinyl toluene, etc. These acrylic monomers are incorporated into the alkyd molecule by addition polymerization. Such alkyds are generally characterized by faster solvent release, quicker tack-free time, better hardness, blocking resistance, color and color retention, and durability, depending on the choice of monomers and amount of acrylic content. These alkyds are also more expensive than conventional alkyds due to higher cost of monomers and the additional manufacturing steps required.

Acrylic latex paint is water-based and dries quickly to a flexible finish, making it ideal for interior and exterior surfaces. Alkyd paint is oil-based and has a longer drying time, providing a durable finish that is resistant to wear and tear. Each type of paint has different properties and uses, so it's important to choose the one that best suits your project.
No, alkyd is not a thermoplastic. Alkyds are a type of synthetic resin commonly used in paints and coatings. Thermoplastics are a different category of materials that can be melted and reshaped multiple times.
It is reasonably reactive. It has been used as a drier for alkyd paints. In that form it was Cerium Octoate.
Yes, you can paint over XIM with any acrylic or alkyd paint. Read the instructions on the can for drying and recoat times.
No, there are some paints, like many water-based paints, that will not block air and moisture and can not be used on metal . Most solvent based paints, like an alkyd or lacquer, over a proper primer, direct to metal water-based acrylics and multi-part epoxies and urethanes can be used over metal successfully.
Alkyd is neither an acid nor an alkaline substance. It is a type of synthetic resin used in the production of paints and coatings, typically made by combining polyols, acids, and vegetable oils.
